| 1 | 肝纤维化中西医结合诊疗指南显示文摘肝纤维化在国际疾病分类(ICD-10)中可作为一种病名(K74-001),但主要是一种组织病理学概念。肝纤维化指肝组织内细胞外基质(ECM)成分过度增生与异常沉积,导致肝脏结构或(和)功能异常的病理变化,结构上表现为肝窦毛细血管化与肝小叶内以及汇管区纤维化;功能上可以表现为肝功能减退、门静脉高压等。其形成机制主要由于肝炎病毒、乙醇、药物与毒物、血吸虫、代谢和遗传、胆汁淤积、自身免疫性肝病等多种损伤因素长期慢性刺激肝脏,使肝窦内肝星状细胞的活化,胶原等ECM成分代谢失衡,生成大于降解,促使肝脏ECM沉积与组织结构重构。 | Liver Disease Committee,Chinese Association of Integrative Medicine. | 2006 | 中华肝脏病杂志2006,14,11: | 269 |
| 2 | The effect of folic acid on the development of stomach and other gastrointestinal cancers显示文摘Objective To evaluate the roles of folic acid and β-carotene in the chemoprevention of gastric and other gastrointestinal (GI) cancers. Methods In a randomized, double-blind, placebo-controlled trial, a total of 216 patients with atrophic gastritis were randomly assigned to one of the four groups: ①folate (FA, 20 mg per day plus vitamin B 12 1 mg, intramuscularly, per month for one year, then 20 mg two times a week plus 1 mg per three months for the next year); ②natural β-carotene (N-βC, 30 mg per day for first year, then 30mg two times a week for the next); ③synthetic β-carotene (S-βC, administered as in N-βC); and ④placebo. Follow-ups continued from 1994 to 2001. Results A total of 7 new cases of gastrointestinal cancers were diagnosed with 3 stomach, 1 colon and 1 esophageal cancers occurring in the placebo group; 1 stomach cancer in both of the N-βC and S-βC groups, and no cancer occurring in FA group. In terms of GI cancers, there was a significant reduction in the FA group, compared with the placebo group (P= 0.04). A similar trend was observed in both N-βC and S-βC groups (P=0.07-0.08). Taken together, the three intervention groups displayed a highly significant decrease in occurrence (P=0.004, vs placebo), and a lower risk for GI cancers (OR=0.12; 95% confidence interval, 0.03-0.51). For development of gastric cancer, any one of the three active-treated groups did not reach statistically significant reduction. The FA group showed obvious improvement of the gastric mucosal lesions with more patients displaying lesions reversed or stable atrophy and inflammation (P=0.04), reversed intestinal metaplasia (P=0.06) at the end of follow-up, and reversed displasia (P=0.017) at 12 months. Two cases of false jaundice were found in β-carotene groups with no influence on administration, and no side-effects were reported in FA group. Conclusions This trial revealed the interventional effect of folic acid on the development of GI cancers, a similar effect of β-carotene was also detected. Also, folic acid may be of use to treat atrophic gastritis by preventing or reversing the precancerous lesions. | 朱舜时 施尧 胡运彪 李蓉蓉 汪敏 周怡和 金冠球 谢宇野Shanghai Navy Hospital Shanghai 200081 China 邬桂泉 夏德凰Shanghai Putuo People's Hospital 钱珍华 宋海连Shanghai Traditional and Western Medical Integrated Hospital 屠伯强 张丽冬 萧树东 | 2003 | Chinese Medical Journal2003,,1: | 42 |

| 5 | Effect of arsenic trioxide on rat hepatocarcinoma and its renal cytotoxicity显示文摘AIM: To study the effect of arsenic trioxide (As2O3) on rat experimental hepatocarcinoma and its renal cytotoxicity.METHODS: The hepatocarcinoma model was established by diethaylnitrosamine perfusion in stomach of 120 Wistar rats, and the treatment began at the end of 20 weeks.Before the treatment, the rat models were randomly divided into 5 groups. In the treatment groups, three doses of As2O3 were injected into rat abdominal cavity, the total time of drug administration was 4 weeks. Cisplatin control or the blank group was injected into abdominal cavity with equal amount of cisplatin or saline at the same time,respectively. On the 7th, 14th and 28th day after the treatment, the hepatocarcinoma nodules were obtained and the morphologic changes of hepatocarcinoma cells were observed under light and electron microscopes;Immunohistochemistry (S-P methods) was employed to detect the expression of bcl-2, bax and PCNA in hepatocarcinoma tissues; flow cytometry (TUNEL assay)was used to detect the apoptosis of liver cancer cells and the change of cytokinetics. On the 28th day, the kidneys were obtained and their histologic changes were observed under light microscope, and immunohistochemistry (SP stain) was also employed to detect the expression of bcl-2and PCNA. Cisplatin and saline solution were used as the control.RESULTS: As2O3 could induce the apoptosis of rat liver cancer cells and exhibited typical morphologic changes.The incidence of apoptosis of hapatocarcinoma cells was elevated (P=0.001). The elevation was the most higher in the group of middle-dose of As2O3 (1 mg.kg-1), significantly higher than that of the other arsenic groups and the controls (P=0.001). Large dose of As2O3 (5 mg.kg-1) was able to arise the incidence of apoptosis, but also produced a large amount of necrosis and inflammatory reaction. Middle dose of As2O3 dramatically increased the cell number in G2/M phase (P=0.0001), and apoptosis happened apparently.The expression of bcl-2 and bax was related to the dose of As2O3. With the up-regulation of apoptotic incidence, the ratio of bcl-2/bak decreased. But the incidence of apoptosis was not the highest status and the ratio of bcl-2/bax was at the lowest when the highest-dose of As2O3 was used.There was significant difference among the PCNA indexes (PCNA L1) of the five groups. Of them, three arsenic groups all showed decrease of different degrees, and this downregulation was most obvious in group A. There was significant difference among the three groups (P=0.016).Under the light microscope, the rat kidney in the cisplatin group exhibited tubular epithelium swelling and degeneration, protein casts in collecting tubules; While all arsenic groups didn't show the significant changes (P=0.013).In the arsenic groups, the expression of bcl-2 in the renal tubular epithelium was increased (P=0.005), no obvious changes happened to PCNA L1. But in the group of cisplatin,the PCNA L1 increased significantly (P=0.001).CONCLUSION: AS2O3 can induce apoptosis of rat hepatocellular carcinoma cells. And there is optimum dose;too high dose will induce the cytotoxic effect, while certain dose of As2O3 is able to block the cell cycle at G2/M phase.As2O3 had the most remarkable influence on G2/M cells,and it can also induce apoptosis to cells at other phases.As2O3 can restrain the proliferation of rat hepatocellular carcinoma cells, in a dose-time dependent manner.Compared with cisplatin, As2O3 didn't show obvious renal toxicity, which was related to the increasing expression of bcl-2 in renal tubular epithelium, the inhibition of apoptosis and the anti-oxidation effects. | Shao-Shan Wang Ti Zhang Xi-Lu Wang Li Hong Department of Surgery of Dagang Hospital 300270,Tianjin,China Qing-Hui Qi Department of Chinese and Western Integral Surgery of Master Hospital of Tianjin Medical University 300052,Tianjin,China | 2003 | World Journal of Gastroenterology2003,9,5: | 17 |
| 6 | Rb1 protects endothelial cells from hydrogen peroxide-induced cell senescence by modulating redox status显示文摘Objectives Endothelial senescence has been proposed to be involved in endothelial dysfunction and atherogenesis. This study investigates the effects of ginsenoside Rbl, a major constituent of ginseng,on H2O2-induced endothelial senescence.Methods Primary human umbilical vein endothelial cells(HUVECs) senescence was induced by H2O2 as judged by senescence-associated P-galactosidase assay (SA-P-gal).Fntracellur superoxide dismutase(S0D1) activity and malondialdehyde(MDA) level were determined by commercial kit.S0D1 mRNA and protein expression were analyzed by real time PCR and Western blot.Reactive oxygen species(ROS) were determined by flow cytometry.Results Rb1 was found to reverse endothelial senescence,as witnessed by a significant decrease of senescent cell numbers. Rbl could markedly increase intracellular SOD activity, decrease the MDA level,and suppress the generation of intracellular ROS in H2O2-treated HUVECs.Consistent with these findings,Rbl can effectively restore SOD1 mRNA and protein expression which decreased in H2O2 treated cells. Conclusions Our report demonstrates thatRbl can exert reversal effects on H2O2-induced cellular senescence through modulating cellular redox status. | LIU Ding-hui~1,CHEN Yan-ming~2,LIU Yong~1,HAO Bao-shun~1, ZHOU Bin~1,WU Lin~1,WANG Min~1,CHEN Lin~1,WU Wei-kang~3,QIAN Xiao-xian~1 (1.Department of Cardiology,The Third Affiliated Hospital of Sun Yat-sen University,Guagnzhou 510630 2.Department of Endocrinology,The Third Affiliated Hospital of Sun Yat-sen, Guagnzhou 510630 3.Institute Integrated Traditional Chinese and Western Medicine,Sun Yat-sen University,Guagnzhou 510630) | 2011 | 岭南心血管病杂志2011,17,S1: | 15 |
| 7 | Effects of silica nanoparticles on growth and photosynthetic pigment contents of Scenedesmus obliquus显示文摘To assess the aquatic ecosystem safety for silica (SiO2) nanoparticles (NPs), the growth inhibition and photosynthetic pigment contents of Scenedesmus obliquus in logarithm growth phase exposed to SiO2 NPs and SiO2 bulk particles (BPs) suspensions were measured. SiO2 NPs with 10-20 nm diameters were found to be toxic. The 20% effective concentration (EC20) values for 72 and 96 hr were 388.1 and 216.5 mg/L, respectively. The contents of chlorophyll decreased significantly under moderate and high concentration (50, 100, and 200 mg/L) of SiO2 NPs after 96-hr exposure, but the carotenoids did not. SiO2 BPs were found to be nontoxic up to 200 mg/L. The toxicity of SiO2 NPs probablely due to their sorption to algal cells surface. The results imply that there is potential harm to aquatic environment by using SiO2 NPs, and it should deserve special concern. | Chenxi Wei, Yanbo Zhang, Jing Guo, Bing Han, Xu Yang, Junlin Yuan Hubei Key Laboratory of Genetic Regulation and Integrative Biology, College of Life Sciences, Huazhong Normal University, Wuhan 430079, China. | 2010 | Journal of Environmental Sciences2010,22,1: | 14 |
| 8 | Eco-economic evolution, emergy evaluation and policy options for the sustainable development of Tibet显示文摘As economies and ecological support systems become more interdependent, new disciplines are needed to 'bridge the gap' of understanding between societies and nature. It is now clear that neither ecology nor economics alone can address the problems of our global commons. New measures of wealth, of value, of contributions and production are needed that acknowledge the 'natural capital' and 'ecosystem services' provided from healthy environments. A new interface is now being recognized termed 'eco-economics'. It is an ambitious and necessary attempt to understand the affairs of humanity and nature as a single, interdependent system. New tools are being invested to measure wealth. services and production fairly and equitably. In this report we use systems analysis approach to study the combined ecological-economic system of Tibet We use an alternative measure of value, based on real contributions to system performance, termed EMERGY, spelt with an 'M'. It is an accounting unit of total contributions, direct and indirect. used in generating a product or service. It is a concept derived from understanding whole systems, their interactions and interdependence, and the resources driving and maintaining them. This broader approach will help us to investigate Tibetan resources utilization and potentialities and exchange. Emergy analysis allows comparison and incroporation of environmental costs and benefits with variables of traditional economic costs and benefits to provide a more comprehensive perspective for public policy directives. Through this research, we think: 1) China has made a great effort in making Tibet develop from a closed regional system to a more and more opened regional system which is very important to the sustainable development of Tibet. 2) The increase of economic development and population growth has a close relationship with the total emergy storage and use in transportation. Education in modern science and technology increased the shared emergy of Tibetans to modern science and technology and stimulated the process of matching material and energy imports from outside with local resources. 3) There is great potential to develop hydropower and geothermal reserves that may stimulate not only economic development but also the better use of environment. 4) The better trained population can increase the empower of Tibet eco-economic system. Future development needs all kinds of talent exchanges with the outside system to develop education. 3) Compared with the Tibet economic system, Taiwan economic system is much more competitive. GNP and emergy use are very useful functions for comparing the competitive power of different ecological economic systems. | YAN Mao-chao, H. T.

| 10 | Run off-on-out method and models for soil infiltrability on hill-slope under rainfall conditions显示文摘The soil infiltrability of hill-slope is important to such studies and practices as hydrological process, crop water supply, irrigation practices, and soil erosion. A new method for measuring soil infiltrability on hill-slope under rainfall condition with run off-on-out was advanced. Based on water (mass) balance, the mathematic models for soil infiltrability estimated from the advances of runoff on soil surface and the water running out of the slope were derived. Experiments of 2 cases were con-ducted. Case I was done under a rainfall intensity of 20 mm/h, at a slope gradient of about 0° with a runoff/on length (area) ratio of 1 : 1. Case II was under a rainfall intensity of 60 mm/h and a slope of 20° with a runoff/on length (area) ratio of 1 : 1. Double ring method was also used to measure the infiltrability for comparison purposes. The experiments were done with soil moisture of 10%. Required data were collected from laboratory experiments. The infiltrability curves were computed from the experimental data. The results indicate that the method can well conceptually represent the transient infiltrability process, with capability to simulate the very high initial soil infiltrability. The rationalities of the method and the models were validated. The errors of the method for the two cases were 1.82%/1.39% and 4.49%/3.529% (Experimental/Model) respectively, as estimated by comparing the rainfall amount with the infiltrated volume, to demonstrate the accuracy of the method. The transient and steady infiltrability measured with double ring was much lower than those with this new method, due to water supply limit and soil aggregates breaking down at initial infiltration stage. The method can overcome the short backs of the traditional sprinkler method and double ring method for soil infil-traility. It can be used to measure the infiltrability of sloped surface under rainfall-runoff-erosion condi-tions, in the related studies. | LEI Tingwu1,2, LIU Han1, PAN Yinghua3, ZHAO Jun2, ZHAO Shiwei2 & YANG Yonghui2 1.

| 11 | Medaka fish stem cells and their applications显示文摘Stem cells are present in developing embryos and adult tissues of multicellular organisms. Owing to their unique features, stem cells provide excellent opportunities for experimental analyses of basic developmental processes such as pluripotency control and cell fate decision and for regenerative medicine by stem cell-based therapy. Stem cell cultures have been best studied in 3 vertebrate organisms. These are the mouse, human and a small laboratory fish called medaka. Specifically, medaka has given rise to the first embryonic stem (ES) cells besides the mouse, the first adult testis-derived male stem cells spermatogonia capable of test-tube sperm production, and most recently, even haploid ES cells capable of producing Holly, a semi-cloned fertile female medaka from a mosaic oocyte created by microinjecting a haploid ES cell nucleus directly into a normal oocyte. These breakthroughs make medaka a favoring vertebrate model for stem cell research, the topic of this review. | YI MeiSheng1, HONG Ni1, LI ZhenDong1, YAN Yan1,2, WANG DanKe1, ZHAO HaoBin1,3 & HONG YunHan1,4* 1Department of Biological Sciences, National University of Singapore, 10 Kent Ridge Crescent, Singapore 119260, Singapore 2Division of Bioengineering, School of Chemical and Biomedical Engineering, Nanyang Technological University, Singapore 637457, Singapore 3Hubei Key Laboratory of Genetic Regulation and Integrative Biology, School of Life Sciences, Huazhong Normal University, Wuhan 430079, China 4State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010,53,4: | 10 |

| 14 | Dissolution theory of gold in alkaline thiourea solution(Ⅲ) ——Thermodynamics on dissolution of gold in alkaline thiourea solution containing Na _2SO_3显示文摘The oxidants of gold were investigated in an alkaline thiourea solution containing Na 2CO 3, in which Na 2S 2O 8 is a proper oxidant for dissolving gold because of in such homogeneous sulfur system coexisting complex agent, oxidant and stabilizing agent. The thermodynamic analyses were conducted on the dissolving of gold in the alkaline thiourea solution containing Na 2SO 3 by the oxidants oxygen or Na 2S 2O 8. The results show that the possibility of gold dissolution reduces with increasing pH value, while oxygen acts as oxidant; and when Na 2S 2O 8 acts as the oxidant of gold in the alkaline thiourea solution of pH 12.5, decomposition potential of thiourea decreases from the standard value 0.42 V to -0.32 V, also the dissolution trend of gold enhances with shifting the mix potential of the solution to the positive direction. | Chai Liyuan(柴立元) 1, Masazumi Okido 2 1.

| 15 | Family integrated care:Supporting parents as primary caregivers in the neonatal intensive care unit显示文摘Family integrated care (FICare) is a collaborative model of neonatal care which aims to address the negative impacts of the neonatal intensive care unit (NICU) environment by involving parents as equal partners, minimizing separation, and supporting parent-infant closeness. FICare incorporates psychological, educational, communication, and environmental strategies to support parents to cope with the NICU environment and to prepare them to be able to emotionally, cognitively, and physically care for their infant. FICare has been associated with improved infant feeding, growth, and parent wellbeing and self-efficacy;important mediators for long-term improved infant neurodevelopmental and behavioural outcomes. FICare implementation requires multi-disciplinary commitment, staff motivation, and sufficient time for preparation and readiness for change as professionals relinquish power and control to instead develop collaborative partnerships with parents. Successful FICare implementation and culture change have been applied by neonatal teams internationally, using practical approaches suited to their local environments. Strategies such as parent and staff meetings and relational communication help to break down barriers to change by providing space for the co-creation of knowledge, the negotiation of caregiving roles and the development of trusting relationships. The COVID-19 pandemic highlighted the vulnerability within programs supporting parental presence in neonatal units and the profound impacts of parent-infant separation. New technologies and digital innovations can help to mitigate these challenges, and support renewed efforts to embed FICare philosophy and practice in neonatal care during the COVID-19 recovery and beyond. | Chandra Waddington Nicole Rvan Veenendaal Karel O’Brien Neil Patel for the International Steering Committee for Family Integrated Care | 2021 | Pediatric Investigation2021,5,2: | 9 |
| 16 | Threshold quantum secret sharing between multi-party and multi-party显示文摘A threshold quantum secret sharing (TQSS) scheme between multi-party and multi-party was proposed using a sequence of single photons,which is useful and efficient when the parties of communication are not all present. We described the process of this TQSS scheme and discussed its security. It was shown that entan-glement is not necessary for quantum secret sharing. Moreover,the theoretic effi-ciency was improved to approach 100% as almost all the instances can be used for generating the private key,and each photon can carry one bit of information. This protocol is feasible with the present-day technique. | YANG YuGuang1,2,3 & WEN QiaoYan4 1 College of Computer Science and Technology,Beijing University of Technology,Beijing 100124,China 2 State Key Laboratory of Integrated Services Network,Xidian University,Xi’an 710071,China 3 State Key Laboratory of Information Security (Graduate University of Chinese Academy of Sciences),Beijing 100049,China 4 State Key Laboratory of Networking and Switching Technology,Beijing University of Posts and Tele-communications,Beijing 100876,China | 2008 | Science China(Physics,Mechanics & Astronomy)2008,51,9: | 8 |
| 17 | Shape optimization of 3D curved slots and its application to the squirrel-cage elastic support design显示文摘The squirrel-cage elastic support is one of the most important components of an aero-engine rotor system.A proper structural design will favor the static and dynamic performances of the system.In view of the deficiency of the current shape optimization techniques,a new mapping approach is proposed to define shape design variables based on the parametric equations of 3D curves and surfaces.It is then applied for the slot shape optimization of a squirrel-cage elastic support.To this end,an automatic design procedure that integrates the Genetic Algorithm (GA) is developed to solve the problem.Two typical examples with different shape constraints are considered.Numerical results provide reasonable optimum designs for the improvement of stiffness and strength of the squirrel-cage elastic support. | WANG Dan,ZHANG WeiHong*,WANG ZhenPei & ZHU JiHong Engineering Simulation and Aerospace Computing,The Key Laboratory of Contemporary Design & Integrated Manufacturing Technology,Northwestern Polytechnical University,Xi’an 710072,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010,53,10: | 8 |

| 20 | Induction of nicotine in tobacco by herbivory and its relation to glucose oxidase activity in the labial gland of three noctuid caterpillars显示文摘Tobacco Nicotiana tabacum L. is a host plant of Helicoverpa armigera (Hübner), Helicoverpa assulta Guenée and Spodoptera litura (Fabricius) (Lepidoptera, Noctuidae). The difference in leaf nicotine response to the feeding by these three larvae and the mechanical simulation of their feeding was examined by HPLC. Results indicated that nico- tine induction was suppressed by H. armigera and H. assulta larvae feeding or by simulated damage treated with their labial glands extracts. The production of nicotine was also suppressed by the glucose oxidase from Aspergillus niger when it was treated on mechanically wounded leaf area. On the contrary, the nicotine production was stimulated by S. litura larva feeding or by simulated damage treated with its labial gland extract. Heat denature can not counteract the stimulation effect of the S. litura labial gland extracts to to- bacco nicotine production. The glucose oxidase activity was detected in labial gland extracts of both H. armigera and H. assulta, but the activity in H. armigera was significantly higher than that in H. assulta. No glucose oxidase activity was detected in labial gland extracts of S. litura. It is shown that the glucose oxidase activity in labial glands of caterpil- lars plays an important role in the nicotine response to her- bivory. The glucose oxidase was mainly contained in the la- bial gland of H. armigera larva, and had the highest activity at pH 7.0. D-Glucose was the optimal substrate of the glucose oxidase. Labial gland glucose oxidase activities varied daily during larval development with high activities found when larvae were actively feeding. | ZONG Na1,2 & WANG Chenzhu1 1.State Key Laboratory of Integrated Management of Insects & Rodents,Institute of Zoology,Chinese Academy of Sciences,Beijing 100080,China 2.Graduate School of Chinese Academy of Sciences,Beijing 100080,China Correspondence should be addressed to Wang Chenzhu(e-mail: czwang@ioz.ac.cn) | 2004 | Chinese Science Bulletin2004,49,15: | 7 |
